However, in the query "and" has a higher priority than "or". Hence, any ShipNotice element is sufficient to end the window. I suggest to force precedence in the query as follows: declare variable $seq := fn:doc("cxml.xml"); <result>{ for sliding window $w in $seq/sequence/* start $s when $s[self::OrderRequest] end $e when $e/@orderID eq  $s/@orderID and ( $e[self::ConfirmationRequest] and $e/@status eq "reject" or $e[self::ShipNotice] ) where $e[self::ShipNotice] return <timeToShip orderID="{ $s/@orderID}">{xs:dateTime($e/@date) - xs:dateTime($s/@date) }</timeToShip> }</result> 44947 1 matthias.brantner 2011-02-01 14:31:16 +0000 Closing as duplicate of bug #11762 *** This bug has been marked as a duplicate of bug 11762 ***
